How the Driver's License format works
- Format
- 1 letter followed by 12 digits
- Example
- A123456789012
Things to watch for
- Format-only check — does not confirm the license actually exists, is valid, or is registered to a real driver
- The number encodes no checksum digit we verify; the leading letter is typically derived from the holder's last name but has no fixed rule we check
- Runs entirely in your browser — nothing you type is transmitted or stored
^[A-Z]\d{12}$A Florida driver’s license number is one letter followed by 12 digits — e.g. A123456789012 — issued by the Florida Department of Highway Safety and Motor Vehicles (DHSMV), making it one of the longest license-number formats in the country. Florida is also one of a handful of states, alongside Illinois, Michigan, Maryland, and Wisconsin, where that leading letter is typically drawn from the first letter of the holder’s last name under a long-standing issuance convention rather than assigned at random.
What this checker verifies
This tool confirms the input is exactly one letter followed by 12 digits, which is enough to catch a missing digit, an extra character, or digits swapped for the leading letter. It does not attempt to verify that the letter actually matches any particular surname — that convention isn’t something a format check can confirm from the number alone.
What a pass doesn’t confirm
Florida’s number carries no check digit this tool recomputes, so a correctly shaped 13-character string is the limit of what a browser-only check confirms. It doesn’t confirm DHSMV actually issued that number, that the license is currently valid, or that it belongs to a real driver, and nothing you type is decoded or stored.
Scope: format-only validation, entirely client-side.

Driver's License FAQ
What is the format of a Florida driver's license number?
One letter followed by 12 digits, e.g. A123456789012, issued by the Florida Department of Highway Safety and Motor Vehicles (DHSMV) — one of the longer license-number formats among US states.
Does the leading letter mean anything on a Florida license?
It's typically derived from the first letter of the holder's last name under DHSMV's issuance convention, but this checker doesn't verify that encoding — any single letter followed by 12 digits passes the format check.
Does a valid format confirm the license belongs to a real person?
No. It only confirms the string is a letter followed by 12 digits. Confirming who, if anyone, actually holds that number requires DHSMV's own records.
